This batch (Sample ID 1150824) from New Zealand Honey Co. Limited has a UMF grade of 15.5 and was independently tested by Hill Labs in New Zealand. UMF is a trusted grading that reflects the unique manuka factors used to certify quality. The laboratory found MGO (methylglyoxal) at 541 mg/kg — MGO is the compound most associated with manuka’s antibacterial activity — and reports leptosperin at 470 mg/kg, a botanical marker used to confirm genuine manuka origin. DHA, which the lab may measure, is the natural precursor that converts into MGO as honey matures. With an MGO above 500 mg/kg and a solid UMF 15.5, this is a higher-strength manuka honey often chosen for applications that value stronger antibacterial properties, such as certain beauty and skin routines, and for people who prefer a more potent everyday product. New Zealand Honey Co. Limited have backed this batch with independent testing, so shoppers can feel confident in its provenance and grade.

In short: UMF 15.5, MGO 541 mg/kg, leptosperin 470 mg/kg — independently tested by Hill Labs (New Zealand) — a premium, higher-strength manuka from New Zealand Honey Co. Limited.
